full resolution scanned documents are kept always as files on the hard disk - the raster data is never loaded to RAM, so it does not compete for the computer resources;

SuperEdit shows views that are calculated on as needed basis according to the current zoom extents and resolution requirements;

nominal parameters like orientation, scale, units, insertion point, are used in order to present the views correctly mapped into world coordinates system;

the DWG, DXF and HPGL vector drawings can be shown as view-only subdocuments;

all raster and vector subdocuments are always registered properly in the same world coordinate system and can be zoomed and scrolled simultaneously using SuperEdit commands or standard MS Windows interface;

SuperEdit provides tools for controlling and editing of raster images, primarily by defining the coordinates system for them and providing tools for clearing selected areas of raster, cut / copy / paste / merge editing, and more advanced operations like resizing, rotating and multi-point calibration of raster images;

SuperEdit provides tools for drafting that may be used to create new lines, symbols, texts and other entities that are kept in TVD drawings; SuperEdit drafting tools may use selective raster snaps; more advanced vectorization is supported by tracing raster lines;

SuperEdit may insert selected vector entities to raster images and rasterize whole vector drawings or composite documents creating new raster images;

both raster and vector drawings can be printed together as one hybrid document using the standard Print command.
